Two keys are displayed on one click when using alternative layout

Hello! I am a new user to Overkeys. I have noticed that when I use an alt layout it does display the key that I pressed and another random key (yet the same random key every time).

I used the regular setting to adjust the layout. I am using Colemak-DH Matrix

As an example, when I press the 't' key (in Colemak-DH), the 'f' key (in Colemak-DH) also shows the press animation.

I am on Windows 11 Pro 25H2

Thanks!

Reproduce the issue on Windows 11 using the Colemak-DH Matrix layout, pressing the reported 't' key and checking the duplicate animation. Trace the keyboard-layout mapping and key-display handling; done means each physical key press shows only its corresponding key animation.
